According to Genesis 31, Rachel takes the teraphim belonging to her father Laban when her husband Jacob escapes. She hides them in a saddle bag and sits on them when Laban comes looking for them, and claims that she cannot get up because she is menstruating. From this it can be deduced that they were small, perhaps 30–35 cm.[4]

In 1 Samuel 19, Michal helps her husband David to escape from her father Saul. She lets him out through a window, and then tricks Saul's men into thinking that a teraphim in her bed is actually David. This suggests the size and shape is that of a man.[5] It also refers to "the" teraphim, which implies that there was a place for teraphim in every household. Van der Toorn claims that "there is no hint of indignation at the presence of teraphim in David's house."[6] However, the same word is used in 1 Samuel 15:23 where Samuel rebukes Saul and tells him that "presumption is as iniquity and teraphim". Here the idea is that rebellion is just as bad as teraphim, the use of which is thus denounced as idolatry.

The teraphim were outlawed in Josiah's reform (2 Kings 23:24), but are mentioned again in Hosea 3:4, where it says that "the Israelites will live many days without king or prince, without sacrifice or sacred stones, without ephod or teraphim." As in the narrative of Micah's Idol the teraphim is closely associated with the ephod, and both are mentioned elsewhere in connection with divination;[1] it is thus a possibility that the Teraphim were involved with the process of cleromancy.

In Zechariah 10:2 it states: "For the teraphim utter nonsense, and the diviners see lies; the dreamers tell false dreams, and give empty consolation.
Therefore the people wander like sheep; they are afflicted for want of a shepherd."

Josephus mentions that there was a custom of carrying housegods on journeys to foreign lands,[7] and it is thus possible that the use of teraphim continued in popular culture well into the Hellenic era and possibly beyond[3]

According to Targum Pseudo-Jonathan, Teraphim were made from the heads of slaughtered first born male adult humans, shaved, salted, spiced, with a golden plate placed under the tongue, and magic words engraved upon the plate; it was believed that the Teraphim, mounted on the wall, would talk to people.[3] During the excavation of Jericho by Kathleen Kenyon, evidence of the use of human skulls as cult objects was uncovered, lending credence to the Rabbinical conjecture.[8] The implied size and the fact that Michal could pretend that one was David, has led to the Rabbinical conjecture that they were heads, possibly mummified human heads.[1]

Casper Labuschagne claims that it comes via metathesis from the root פתר, "to interpret".[9] Karel Van der Toorn argues that they were ancestor figurines rather than household deities, and that the "current interpretation of the teraphim as household deities suffers from a onesided use of Mesopotamian material."[10]

That Micah, who worshipped Yahweh, used the Teraphim as an idol, and that Laban regarded the Teraphim as representing his gods, is thought to indicate that they were evidently images of Yahweh.[3] It is considered possible that they originated as a fetish, possibly initially representative of ancestors, but gradually becoming oracular.[3]
